Purpose
To report the visual, refractive, and keratometric changes after INTACS implantation for keratoconus.
Setting
Cleveland Clinic Abu Dhabi
Methods
Retrospective chart review of records between March 2016 and September 2019 at the Cleveland Clinic Abu Dhabi. All INTACS SK rings were inserted using a femtosecond laser according to the manufacturer’s recommendations. Visual, refractive, and keratometric changes, along with surgical complications, were analyzed
Results
Sixty seven eyes of 67 keratoconus patients aged 18 to 47 (average 29) years were included. Thirty-eight were male and 38 had their right eyes operated on. Seventeen had prior collagen cross-linking and 2 had previous PRK. The mean follow-up duration was 7.5 months. Statistically significant improvement was noted in uncorrected visual acuity (preop LogMAR 1.00 to postop 0.55), best-corrected acuity (0.30 to 0.20), spherical equivalent (8.29D to 5.43D), sphere (-6.59D to -3.94D), and cylinder (3.52D to 3.16D). On keratometry, SimK improved from 49.08D to 46.58D (p<0.001) and Kmax from 55.19D to 52.30D (p,0.001), however corneal astigmatism improved from 4.15D to 3.85D which was not significant (p=0.27). No complications were noted.
Conclusions
INTACs implantation resulted in significant improvement in visual, refractive, and keratometric outcomes in our patients, which is consistent with prior literature.
